MARTIN S. MOOT, OF NEWV YORK, N. Y.

SOAP COMPOUND.

SPECIFICATION forming part of Letters Patent No. 340,451, dated April 20, 1886.

Application filed December 31, 1885. Serial No.-187.218. (Specimens) To all whom it may concern: b

Be it known that I. ll/IARTIN S. Moor, of the city and county of New York, in the State of New York, have made a new and useful Improvement in the Manufacture of Soap Compounds; and I do declare that the following is a full and exact description thereof.

I have discovered that by using a pure neutral soap in which is no rosin or' other foreign a fourth pound of rosin per gallon.

material, with a sufficient quantity of water to reduce it to the condition ofsoft soap, Ican combine a large quantity of rosin previously dissolved in naphtha, and that the resulting compound has peculiar qualities.

My soap compound will wash and cleanse clothing with little labor, and will not injure the. clothing any more than common soap. It should be used'in the form of a strong suds, preferably hot, soaking the clothes in it from twelve to twenty-four hours. They can then be wrung out with a wringer and examined. If there are specially soiled places those places should be then treated with the rubbingboard and common soap; but it will he found in ordinary cases that the articles will need but little more attention than simply rinsing to remove the compound, and then drying.

To manufacture my compound, I dissolve one and a quarter pound of hard or soda soap in two quarts of water, with or without heat. It I use heat, I let it cool off to common temperature. Now, take naphtha or any other of the light oils of distillation of co \1 or petroleum, and dissolve therein from one to one and Of this I take from one and a fourth to one and a half pint and thoroughly mix with the above quantity of soapand water, a little at a time, at common temperatures, by gently stirring. It mixes readily. I must combine these substances to saturation in order to get the best results. The soap to commence with must not contain'rosin. It must contain nothing but the alkali and fatty acids. I let the compound stand a short time, and if it smells strongly of the hydrocarbon more of the dissolved soap contains rosin will not serve as well.

should be added. It is better to have the soap in excess than the hydrocarbon. The combining of the hydrocarbon and rosin with the soap forms volatile substances, and if these are allowed to escape by either rapid or slow evaporation the quality of the product is greatly impaired.

The above description presupposes that the soap primarily dissolved is good soda soap in a practically neutral condition. If potash soap is used no water is needed.

My solution of light hydrocarbon oil and rosin will improve any soap; but a soap that I think it may be correctly set forth as essential to the full realization of my invention that the soap to commence with should be practically pure.

I use the term naphtha to indicate any of the light products of the distillation of coal or petroleum.

The best effect is produced by a suds formed by dissolving one quart of the compound in eight gallons of hot water.

My experiments indicate that the com pound acts on the skin too severely to allow the hands to be much immersed in the suds at this strength.

I claim as my invention 1. The process described of dissolving rosin in light hydrocarbon oil and gradually mixing with soup at common temperatures ,in the presence of a small quantity of water, substantiallyas herein specified.

2. The compound described of soap and water, naphtha and rosin, combined in the manner and substantially in the proportions herein specified.

In testimony whereof I have hereunto set my hand, at New York city, New York, this 30th day of December, 1885, in the presence of two subscribing witnesses.
